RADIATOR-FITTING.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application led October 4, 1917. Serial No. 194,764.

To all whom t may concern:

Be it known that I, FRANK MEYERS, a citizen of the United States, residing atv Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Radiator-Fittings, of which the following is a speciiication.

rIhis invention relates to radiators and it is the principal object of the invention to provide an improved return pipe iitting therefor, whereby steam or vapor will be positively prevented from passing from the radiator into the return pipe.

Another object of the invention is to provide a novel form of fluid seal in the connection between the radiator outlet and the return pipe.

The foregoing together with additional advantageous details and arrangement of parts of the preferred embodiment of my invention will be clear from the specific description hereinafter contained, when read iu connection with the accompanying drawings forming part thereof, wherein said embodiment oi the invention is illustrated for the purpose ot' facilitating a full understanding ot the present improvements.

In the drawings:

Figure l is a vertical section through the improved litting anda fragment of a radiator loop; and

Fig. 2 is an end .elevation ot the improved fitting.

I-Iaving more particular reference to the drawings and in connection with which like reference characters will refer to corresponding parts in the several views, 1 represents a fragment ot a radiator loop having a screw threaded out-let opening 2 formed in` one side thereof, whereby connection between the usual form ot' return pipe may be effected.

'.lurned into engagement with the screw threaded outlet opening 2 is an eccentric bush ing 3, which bushing is adapted to have a short conduit t turned into engage-ment therewith, the outer marginal edges of which are beveled as at 5 and elbow 6 also provided with beveled edges is engaged with the beveled edges 5 of the short conduit 4 and is connected thereto through the me dium of a union nut 7 it of course being understood that the said elbow 6 is connected to the usual return pipe included in the heat distributing system. That end of the short conduit i which is lturned into engagement with the eccentric bushing 3 is partially closed by an end piece 8 formed integral therewith and having a screw threaded opening and a'slot 9 extending therethrough whereby a vent will be provided.

Passing through the elbow 6, the short conduit 4 and the screw threaded opening formed in the end piece S is a conduit 9 having the vopposite ends thereof curved as at l0, which curved ends are arranged in the elbow 6 and the radiator loop, it being noted that the curved end l0 arranged in the said radiator loop is arranged below the water line therein. To prevent undue movement of the tube 9, the intermediate portion of the same is screw-threaded and turned into engagement with the screw threaded opening formed in the said piece 8.

From the foregoing, it will be readily underst-ood by those skilled in the art that with my improved connection the escape of steam or vapor from a radiator provided with the same is positively prevented, since, the tube 9 with its cur Ted ends 10 is so arranged as to prevent the passage of the steam or vapor thereinto. Thus, the eiiiciency of the radiator is materially increased.

The connection by reason or its exceedingly simple construction may be arranged upon the conventional type of radiators without material alteration thereto and in but a minimum amount of time.

Manifestly, the construction shown is capable of Considerable modification and such modification as is within the scope of my claims, I consider within the spirit ot my invention.

I claim 1. In combination with. a radiator and the return pipe therefor, a short conduit turned into engagement with the radiator outlet opening and having one end partially closed, the remaining end of the short con-- duit being connected to the return pipe and a tube having its opposite ends curved passing through said short conduit into entheradiator outlet having one end partially closed, Athe remaining end vof said Conduit being connected to the return pipe, and a tube having its opposite ends curved diOWn- Wardly passing through said conduit into engagement With the radiator and the rel0 turn pipe, one end of the tube being Varranged beloW the Water line in the radiator.

In testimony whereof, I afx my Signature hereto.

FRANK AMEYERS.
